This little car won the 2005 Shell Eco-marathon, setting a world record of 5,385 km per liter of fuel. (That's a mind-boggling 12,862 miles per gallon!) Designed and developed by students and staff of the Swiss Federal Institute of Technology Zurich, the 3-wheeled car is powered by a hydrogen fuel cell.
The Shell Eco-marathon was established to challenge young people to design, build and race energy-efficient vehicles. The goal of the competitors is to drive as far as possible using the least amount of energy.
